Reflection, refraction and lenses
Flashcards do conjunto (9)
- 1Reflectioninstead of passing through a media, the waves will bounce back
- 2Name three examples of reflection?-sound waves reflected off of walls and buildings (echos)
-dolphins and bats monitor their surroundings (echolocation)
-radio waves reflected from surfaces within the atmosphere such as the ionosphere - 3Refractionthe bending of light rays at a surface
- 4Why does refraction occur?the speed of the wave length changes as it passes through different materials because of the change of density
- 5What happens when the light travels to a less dense material?the wave speeds up, causing it to bend away from the normal
- 6What has occurred in this image?The wave has been refracted. The material is more dense, so the wave slows down, causing it to bend towards the normal
- 7What type of lens is this?Converging lens
- 8Uses of converging lenses?Telescopes, projectors, cameras, binoculars, our eyes
- 9What type of lens is this?Diverging lens
